Marker-free real-time needle tracking for CT-guided procedures utilizing multiple RGB cameras

1

The proposed system utilizes low-cost RGB cameras for marker-less, real-time needle tracking in CT-guided interventions.
2

It achieves clinically accurate tracking for various needle types without requiring modifications or recalibration.
3

The system was evaluated against established marker-based systems under challenging conditions, demonstrating superior performance.
4

A publicly available dataset of over 35,000 annotated frames supports the development of needle tracking solutions.
5

This research addresses significant limitations in existing tracking systems, enhancing clinical utility in minimally invasive procedures.
